It is different because the wells are physical property. If you don't pay the loan back, the bank gets the stock options. No affect to the company really. If the loan isn't paid in this case the bank puts a lein against the wells. This will force CHK to pay back his personal loans or risk the court forcing them to sell some wells.
Who cares, the CEO should NOT have been doing this. What else is going on behind the scenes that the public doesn't know about?? That's WHY I sold at 17.44, and took a terrible hit on the stock. This news alone could send CHK below 10!!!
